RockmanForte: I see your bios comes up as unknown too, which is why I asked the on the blog for more information on the bios required to give the "BIOS Valid" message I am seeing in the .exe hex code. I bet the file sizes don't match the image on this page either:http://www.neonds.com/en/en-help

So again, is yours coming up with "BIOS Valid" or not? Mine is emulating fine as long as they are present and named correctly, even if it doesn't think they are valid. It crashes if they aren't named correctly when trying to run something.

I'd still like to hear the developers info on what CRC of bios checks out in the emulator, what size the files that it expects should be or whether the check itself is just plain broken.
